Description
Technical field
The present invention relates to a kind of monitoring method of rail vehicle component and monitoring systems, more particularly, to one kind based on wide
The rail vehicle axle health status monitoring method and monitoring system of domain net and local area network, this kind of monitoring method and monitoring system can
Big data central monitoring is carried out to rolling stock axle (including bearing) health status and vehicle braking state, belongs to rail vehicle
Monitor control technology field.
Background technique:
Currently, rail vehicle (including railway freight-car, car etc.) axle bearing in China's is because by different loads, difference operation line
Road, packaging technology, the influence of the factors such as quality itself, longtime running will likely can generate various types of (hot axis) failures, such as
Fruit can not find and exclude in time to bearing fault, it will seriously endanger the traffic safety of rail vehicle, rolling stock
On the axle bearing that uses once accident occurs, can not only cause damage of the bearing, and be possible to interfere train operating safety,
For the high reliability and safety for ensuring train operation, require vehicle bearing have various performances；So in rail vehicle
In operational process, unmanned remote system monitoring management is carried out to the state knot of its axle (hot axis) failure, finds track in time
The failure of Vehicle Axles, takes corresponding measure, it is ensured that vehicle safety operation has great meaning.
It and is all using active detection side currently, being primarily only to be confined to train or car to the detection of rail vehicle
Formula；Axle status monitoring is broadly divided into vehicle-mounted contact measurement and ground based IR measurement.This detection mode is all based on external electrical
The sensor of source power supply obtains signal, then is transmitted to control system, carries out the monitoring mode of analysis and Control；But this mode pair
It is just not applicable for passive lorry, therefore the bearing monitoring for how solving lorry axle is always one long-standing
The problem of, and the lorry probability that accidents happened accounts for a greater part of of entire accident now.Axis on China Railway Freight train at this stage
Warm detection device is mainly used one is contactless infrared journal temperature detection system, is by installing infrared probe every 30km
Axis temperature is detected.But this mode is being easily affected by the external environment, due to location difficulty etc., so that the excessively high announcement of axis temperature
Alert encashment ratio is low, rate of false alarm is high, and cost is very high, so being badly in need of solving this.
By patent retrieval do not find have with the patent literature report of same technique of the present invention, have certain relationship with the present invention
Patent mainly have it is following:
1, Patent No. CN201610850367.1, a kind of entitled " train axle state based on surface acoustic wave techniques

Train axle state monitoring apparatus can complete the comprehensive real-time monitoring to train axle state, and carry out shifting to an earlier date for failure
The accurate positionin of early warning and abort situation, and without being laid with cable or fiber optic communications in compartment.
2, Patent No. CN201621080407.0, entitled " the train axle state prison based on wireless sourceless sensor
Survey device " patent of invention, which disclose a kind of train axle state monitoring apparatus based on wireless sourceless sensor, packet
It includes and is set to train head and controls indoor Host Supervision System, be set to the signal reader of each compartment bottom and be mounted on
Surface acoustic wave sensing network on the axle of each compartment bottom, surface acoustic wave sensing network are read and write using radio frequency identification and signal
Device connection, signal reader are connect by wireless network with Host Supervision System.The present invention is based on the column of wireless sourceless sensor
Vehicle axle state monitoring apparatus can complete the comprehensive real-time monitoring to train axle state, and carry out the pre- in advance of failure
Alert and abort situation accurate positionin, and without being laid with cable or fiber optic communications in compartment
3, Patent No. CN201610563239.9, it is entitled " railway freight-car bearing temperature monitoring circuit and its monitoring method "
Patent of invention, which disclose a kind of railway freight-car bearing temperature monitoring circuit, the temperature including being fixed on each compartment is adopted
Collect unit, it is characterised in that: the temperature collecting cell includes sensor module, processor module, wireless transport module and work
Make power supply, the signal output end of the sensor module is connected with the signal input part of processor module, the processor module
Signal output end realized and be wirelessly connected by wireless transport module and train head controller, the working power and processor die
Block connection.
Although some has been related to the method for wagon axle temperature monitoring to these above-mentioned patents, but some is still using active side
Formula is detected, so will be unable to the institute for implementing, and being proposed now for the vehicle as the not no power supply of railroad train this kind
Passive detection mode is called, such as Patent No. CN201621080407.0, entitled " the train vehicle based on wireless sourceless sensor
The patent of invention of Spindle Status monitoring device ", though be known as be it is passive, read over the patent it can be found that the patent still only
It is that the wireless transmission method taken is transmitted to the signal between sensor and control system, signal read-write is realized by wireless network
Device is connect with Host Supervision System, and wireless network, using wireless ZigBee-network, this kind of network is only applicable to low coverage
It is used from the case where, low complex degree, so being at most only suitable for the data transmitting between separate unit train, is not particularly suited for axle
Big data monitoring；So-called passive sensor is using wireless and passive single ended resonant type SAW sensor, so among reality
It can be found that this transmission mode is unworkable.Patent No. CN201610563239.9, entitled " railway freight-car axis temperature
Observation circuit and its monitoring method " though a kind of railway freight-car bearing temperature monitoring circuit and its monitoring method are proposed, by careful
It reads it can be found that also not having practicability, therefore still need further to be improved.
Summary of the invention
It is an object of the invention to propose a kind of new railway goods for deficiency present in existing railway freight-car shaft monitoring
Axle monitoring method, this kind of monitoring method are to combine the lorry axle health status established with local area network using wide area network
Monitoring system, and realize center and the area monitoring's control of lorry axle health status monitoring big data.
It is strong using the above-mentioned lorry axle established based on wide area network and LAN system that the invention further relates to a kind of
Health state monitoring method is formed by lorry axle health status monitoring system and device.
In order to reach this purpose, technical solution proposed by the invention is: a kind of rail based on wide area network and local area network
Road Vehicle Axles health status intelligent monitoring method is combined with local area network to rail vehicle axle health status by wide area network
Timely monitor；When there is wide area network signals covering, the transmission of rail vehicle axle health status signal and prison are carried out using wide area network
Control；When no wide area network signals cover, the transmission of rail vehicle axle health status local signal, monitoring are carried out using local area network,
And implement signal data storage, until when having wide area network signals covering, then by the monitoring signals data stored by local area network, on
Monitoring center is reached, further data are analyzed and handled by monitoring center, realizes rail vehicle axle health status
